Minor errors regarding the released dataset

Make sure you have read FAQ before posting. Thanks! Hello， Sorry to disrupt you again. After reading the FAQ carefully, I downloaded your released datasets, there are some small mistakes here. And there is some problem about launching carla, I guess this problem leads to the errors about training the ego model.

1 datasets lose key and value

For example,

real_file='/home/shy/Desktop/aazijolwvf'
json_file=real_file+'/data.json'
data = json.load(open(json_file))
data['0']
{'loc': [655.82763671875, 30.739931106567383, 0.03367812931537628],
 'rot': [-91.5350341796875],
 'spd': [2.312199831008911],
 'cmd': [4.0],
 'lbl_00': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_00_00000.png',
 'lbl_01': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_01_00000.png',
 'lbl_02': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_02_00000.png',
 'lbl_03': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_03_00000.png',
 'lbl_04': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_04_00000.png',
 'lbl_05': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_05_00000.png',
 'lbl_06': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_06_00000.png',
 'lbl_07': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_07_00000.png',
 'lbl_08': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_08_00000.png',
 'lbl_09': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_09_00000.png',
 'lbl_10': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_10_00000.png',
 'lbl_11': '/ssd2/dian/challenge_data/main_trajs6_converted/aazijolwvf/rgbs/lbl_11_00000.png',
 'wide_rgb_{}': '/rgbs/narr_rgb_2_00000.jpg',
 'wide_sem_{}': '/rgbs/wide_sem_2_00000.png',
 'narr_sem_{}': '/rgbs/narr_sem_2_00000.png'}

It seems that the narr_rgb_{} key and value is lost, and the file name does not correspond to the value in this json file. Besides, the value of wide_rgb_{} is also needs to be changed. So the code here is provided:

import json
real_file='/home/shy/Desktop/aazijolwvf'
#json_file ='/home/shy/Desktop/aazijolwvf/data.json'
json_file=real_file+'/data.json'
json_save_file=real_file+'/data_new.json'
data = json.load(open(json_file))

for i in range(data['len']):
    idx = str(i)
    data[idx]['narr_rgb_{}']=data[idx]['wide_rgb_{}']
    wide_value = data[idx]['wide_rgb_{}'][:6]+'wide'+data[idx]['wide_rgb_{}'][10:]
    #print("wide value is", wide_value)
    data[idx]['wide_rgb_{}']=wide_value

    # data['0'].keys()
    key_change_lbl = [key for key in data[idx].keys()][4:16]
    key_change_rgb=[ [key for key in data[idx].keys()][16],[key for key in data[idx].keys()][19] ]
    key_change_sem=[ [key for key in data[idx].keys()][17],[key for key in data[idx].keys()][18] ]
    for key in key_change_lbl:
        #print("data",data['0'][key])
        real_str = data[idx][key][58:]
        data_new=real_file+real_str
        data[idx][key] = data_new
    for key in key_change_rgb:
    # remove_rgb
        real_str_first= data[idx][key][:10]
        real_str_last= data[idx][key][14:]
        data_new=real_file+real_str_first+real_str_last
        data[idx][key] = data_new

    for key in key_change_sem:
        real_str= data[idx][key]
        data_new=real_file+real_str
        data[idx][key] = data_new
    

with open(json_save_file, 'w') as outfile:
    json.dump(data, outfile)

And for testing, we set a random number, the code is following:

import numpy as np
idx = np.random.randint(0,200)
print("The index is",idx)
idx = str(idx)
key_images= [key for key in data[idx].keys()][4:]
for key in key_images[12:]:
    print(data[idx][key])
    x = plt.imread(data[idx][key])
   # print("x.shape",x.shape)
    plt.figure()
    plt.imshow(x)

And finally the datasets can be loaded.

2 what does 6+:lane centers mean?

I found 6-11 are lane centers,what is the difference between them or how to collect it? I thought the direction of no.11 images seems different, I guess it maybe the people’s lane center?

3 Is Vulcan necessary for Carla?

I failed to launch Carla by running the launch Carla shell. In FAQ, it might be the error of Vulcan, However, I can still launch Carla using the OpenGL. And I successfully test the examples in PythonAPI. After launching Carla, I decided to train the ego_model. And first of all, I need to collect the datasets.

$ ./CarlaUE4.sh -fps 10 -world-port 2000

Then I tried

$ python -m rails.data_phase0 --num-runners=1 --port=2000
(world_on_rails) shy@carla:~/WorldOnRails0526$ python -m rails.data_phase0 --num-runners=1 --port=2000

    raise TypeError(str(exc)) from None
TypeError: missing a required argument: 'route'

I am not sure how to fix this problem, I just do as follows:（Did I set the right scenario_class?）

runner = ScenarioRunner.remote(args,scenario_class='route_scenario', scenario=scenario, route=route, port=port, tm_port=tm_port)

After that, there is no error and it seems that the code is running at ray.wait(jobs, num_returns=args.num_runners), and no data are saved. Then I turned to phase1,

python -m rails.data_phase1 --scenario=train_scenario --num-runners=1 --port 2000
